Structs

BorrowedHandle

A borrowed handle.

HandleOrInvalid

FFI type for handles in return values or out parameters, where INVALID_HANDLE_VALUE is used as a sentry value to indicate errors, such as in the return value of CreateFileW. This uses repr(transparent) and has the representation of a host handle, so that it can be used in such FFI declarations.

HandleOrNull

FFI type for handles in return values or out parameters, where NULL is used as a sentry value to indicate errors, such as in the return value of CreateThread. This uses repr(transparent) and has the representation of a host handle, so that it can be used in such FFI declarations.

InvalidHandleError

This is the error type used by HandleOrInvalid when attempting to convert into a handle, to indicate that the value is INVALID_HANDLE_VALUE.

NullHandleError

This is the error type used by HandleOrNull when attempting to convert into a handle, to indicate that the value is null.

OwnedHandle

An owned handle.
